Remove the mqtt: from the add-on config and move the other lines back so it looks like the serial format.

I’m answering from a phone so can’t type it all out for you

[fleskefjes]

Specify adapter type in the file.

serial:
  port: tcp://192.168.1.244:6638
  adapter: zstack

Did you fix the incorrect mqtt entry in the add-on config?

It won’t work until you do - remove the mqtt:

[miomia]

Check please

[Neil_Brownlee]

That looks better

[miomia]

The result is the same

[Neil_Brownlee]

OK, so it’s saying it can’t talk to your adapter. Is it flashed as a coordinator or a router?
